Answers and some basic facts are presented herein. EI Rev. 1.2 2/20/86 .heThe Word on the Z-System .pa .foQuestion 1: Bringing up ZCPR3 Page # QUESTION 1: Bringing up ZCPR3 --> 1. Is ZCPR3 hard to bring up on my computer? What are my options? ANSWER If you try to bring up ZCPR3 manually (following the installation instructions in ZCPR3: The Manual), the answer is yes. Experience in assembly-language programming is necessary. Source code to your BIOS is necessary. An understanding of CP/M and Z- System concepts is necessary. However, you may not have to bring ZCPR3 manually. There are options... ZCPR3 Installation Options OPTIONS Your basic options are: 1) Manual Installation o no cost (download the software) o complex with many options o requires knowledge of assembly language 2) Automatic Installation (Auto-Install) o commercial products: Z3-DOT-COM (includes all help files and all utilities in COM file form) $ 99.00 Z3-DOT-COM (without utilities) $ 49.95 Z-COM (full Z3-DOT-COM with ZRDOS) $119.00 ZRDOS (CP/M BDOS Replacement) $ 49.50 ZRDOS+ (ZRDOS with Public Dirs) $ 59.50 o write or call Echelon for current prices 3) Pre-installed for specific systems o soon to be released o write or call Echelon for availability/prices o target installations: Ampro Kaypro Eagle Morrow Epson QX-10 Osborne Heath/Zenith Micromint SB180 4) User Groups o major user groups often have complete ZCPR3 o examples: First Osborne user's Group (FOG) Tampa Bay Kaypro User's Group 5) Echelon Good-Neighbor Helper Roster ADDRESSES General: Echelon, Inc. 885 N.

Page # QUESTION 2: How Much Memory is Taken Up by a Z-System? --> 2. How much memory does a Z-System take? ANSWER A Z-System can take up a lot of memory, but it can also take as little as 1K, depending on how it's installed. I have run the following programs in a full-up Z-System (which takes 5K more than a similar CP/M system), and they have worked well for my applications: dBase II BDS C WordStar C/80 SpellStar Pascal/MT+ MailMerge MultiPlan StarIndex ASM, MAC, M80, ZAS MBASIC Z-MSG CBASIC2 There are some programs which hog so much TPA that they can't run under my full-up Z-System, but I don't use them or need them for my applications. The impact on memory is really not that significant if you look at a true picture...

Breakdown of BIOS Overhead Growth BIOS Size Standard CP/M Minimum ZCPR3 Maximum ZCPR3 --------- ------------- ------------- ------------- 1.5K 7K = 10.9% 8K = 12.5% 12K = 18.8% 2.5K 8K = 12.5% 9K = 14.1% 13K = 20.3% 3.5K 9K = 14.1% 10K = 15.6% 14K = 21.9% 4.5K 10K = 15.6% 11K = 17.2% 15K = 23.4% 5.5K 11K = 17.2% 12K = 18.8% 16K = 25.0% Note: nK = p% indicates the size of the system in K (BIOS + BDOS + CPR) and the percentage of the total memory taken up by the operating system. In my case, I am running a Maximum ZCPR3 with a 5.5K BIOS overhead, so this leaves a 48K TPA (64K - 16K System) which expands to 50K if the program overlays ZCPR3. All my programs, including WordStar and dBASE II continue to run, and I have full ZCPR3 features. Even with this argument, people will still ignore the vast gains in functionality and capability offered by ZCPR3 and Z- System and concentrate on their single-minded fixation with TPA (for reasons no one has adequately explained to me). A future ZCPR3 release, ZCPRB3, will offer a banked memory system with at least a 60K TPA (now, that should make them happy). Note that I am not moving to a banked system on their account, but as a step toward multitasking--something I really want. .foQuestion 3: How Much Disk Space is Used? Page # QUESTION 3: Must I have a hard disk to run the Z-System? --> 3. Do I have to have a hard disk to run the Z-System? How much disk space is needed? ANSWER No. The Z-System runs better on a hard disk...because everything runs better on a hard disk. Also, a hard disk runs better on a Z-System because of all the programs and features which support the hard disk: Named directories with passwords Public directories under ZRDOS+ Paths Shells Special commands, like CD (Change Directory) Most Z-System features are practical regardless of the disk used. The following shows some disk configurations, from a full-up hard disk (over 1 megabyte of support files) to a minimum system (less than 40K-bytes of support files)... .pa How Much Disk Space Does a Z-System Require? 1.
